‘Quinn’s injury, first reported by Eilliotte Friedman of TSN, occurred during offseason training. His recovery is expected to take up to six months. The Sabres open the season Oct. 12, fewer than four months from the date of Quinn’s surgery. A full six-month recovery would extend to the end of December, almost 40 games into the season.’
